What happened

Dashed lines are drawn by deck.gl's PathStyleExtension. The deck.gl the page supplied does not export it (the standalone deck.gl bundle does; a build assembled from @deck.gl/core and @deck.gl/layers alone does not), so every route is drawn solid.

The fix

Load the full deck.gl bundle, or pass a deck that includes PathStyleExtension as libs.deck.

The smallest fix

<script src="https://cdn.jsdelivr.net/npm/deck.gl@9.1.0/dist.min.js"></script>
